This is an interesting one; all the phones in our office do not recognize keypad entry only during a call. When dialing out for the first time, or transferring employees internally, all functions of a keypad on the phone works just fine. Once I contact automated service, lets say Verizon, their system asks to input a 10 digit phone number. This is where the keypad on the phone is not recognized. I've attempted to call a few different numbers, with identical situation and all of them did not recognize my keypad.
